This is an out-and-out lie. They are willing to serve me pages without ads, because they do it every time I browse there with an ad-blocker. I make an HTTP request, their site responds. The HTML code asks me to download an ad, and I, through my ad-blocker, decline. That doesn't stop their server from sending me the content.
If they don't like that, they're perfectly free to design their site to force me to download ads in order to view the content. They have every right to, for instance, show me a video ad, and then have me take a quiz to demonstrate that I viewed the ad and remember it, before continuing on to the rest of the site. If they don't want to do this, that's their problem, not mine.
>No ads = they don't exist = no content.
It's not my job to worry about their business model.
>My bet is that companies just find a way around ad-blocking
Well, they could just embed the ads into the page, such as by serving them from the same domain and making it non-obvious which images are ads and which are not. People have been proposing this for ages. But the ad companies don't like it because they don't trust their own clients to accurately report ad-servings. Again, not my problem. They need to fix their own business model. If they can't do that, and go out of business, that's their problem. They should have done a better job coming up with a viable business model.
This may sound greedy to you, but for you to have the absolute gall of telling people that they need to expose their computers to malware is purely asinine.
